Abstract
A cam shaft tool for a slide type lathe. The invention generally comprises an improved adjustable tool wherein a plurality of holders each carrying a cutting insert is fixed to a main block via an adjustment block. The holder is radially adjustable relative to said adjustment block and axially relative to said main block. The invention also relates to a cutting insert holder for use in a cam shaft tool.
Claims12
A cam shaft tool for cutting a plurality of grooves in a rotating work piece which has a longitudinal axis extending in an axial direction, said axial direction being perpendicular to a radial direction, said tool comprising:
- a first block having a plurality of second blocks mounted thereon, said first and second blocks having mating first abutment surfaces for guidance of said second block in said axial direction;
- each said second block carrying a holder having a cutting insert at a radially forward end thereof, each said second block and said holder including mating second abutment surfaces for guidance of said holder in said radial direction;
- a plurality of radial setting means for adjusting said holder relative to said second block in said radial direction;
- a plurality of axial setting means for adjusting said second blocks relative to said first block in the axial direction without affecting the position of said second blocks in said radial direction, said axial setting means including rotatable adjusting pins that extend through holes in said second block and said holder and into a hole in said first block;
- and
- a plurality of fastening means for fixing the relative positions of said holders, said second blocks and said first block.
A cam shaft tool for cutting a plurality of grooves in a rotating work piece having a radial and an axial direction comprising:
- a first block having a plurality of second blocks mounted thereon, said first and second blocks having mating first abutment surfaces for guidance of said second block in said axial direction;
- each said second block carrying a holder having a cutting insert at a radially forward end thereof, each said second block and said holder including mating second abutment surfaces for guidance of said holder in said radial direction;
- a plurality of radial setting means for adjusting said holder relative to said second block in said radial direction;
- a plurality of axial setting means for adjusting said second blocks relative to said first block in said axial direction, one of said axial setting means being provided to adjust each one of said second blocks relative to said first block;
- and
- a plurality of fastening means for fixing the relative positions of said holders, said second blocks and said first block, wherein each axial setting means includes an elongated adjusting pin and a central hole extending through said second block and said holder and at least partly through said first block, said adjusting pin extending through central holes of said second block and said holder and into a central hole in the first block, said adjusting pin having an eccentric enlargement which is received by a non-cylindrical enlargement of the central hole in the second block.
